Converting Emails: Merge & Purge

Over far too many years I had amassed a collection of mail archives with much overlap (but also enough unique emails to keep the different archives) in different formats. This article is about the effort to unify them (merge), and eliminate (most) duplication, delete emails older than my new ‘personal data retention policy’ (purge), and organize what was left into yearly archives so that it is easy to annually remove no longer relevant emails.

Lightweight Public Git Self Hosting

Public git self hosting can be desirable for a number of reasons, but you may not want the expense and maintenance burden of a GitLab or other ‘full-service’ git hosting options, so this article discusses a lightweight option for a browsing or cloning your git repositories via HTTP/HTTPS (web), as well as pushing, pulling, cloning, etc using SSH.

At the very least it gives you a way to keep a backup you control of your valuable source code and documents that are also on a large central service.

Fast Cross-Compile of Linux 2.6 for Armel

Unless you have new, high-powered, ARM system to build with, the fastest and most practical way to build software for armel (early ARM CPU versions) is to
cross-compile on an x86_64 machine (Debian and offshoots call this the amd64 architecture, even for non-AMD CPUs). This article is specifically about buildinga Linux 2.6 kernel. Obtaining a working toolchain that is able to build this old a kernel is probably the hardest part of the exercise. This supersedes

Windows in a Libvirt KVM VM

These are some updated personal notes about setting up the Windows side of a nice combined Windows and Linux productivity and development environment in Virtual Machine running under Libvirt Qemu/KVM (that is with Linux as the host OS). It uses open source software combined with some key proprietary pieces on a single machine. It is important to note this environment is geared to those who are used to the Linux ecosystem and also want to use or try the new hybrid model.

Raspberry Pi OS for a Server

For small deployments (or home or small office use) you may find yourself in need of a ‘bare metal’ server, but not want or need the expense of an x64 machine. If the workload is not too demanding, a Raspberry Pi can be a good choice. The Pi has the benefit of being inexpensive, using little electricity, and taking little space. This article has been modified to use Raspberry Pi OS as the base instead of a customised Raspbian image.

Archives: Linux Network Monitoring

I’ve added back my Linux Network Monitoring presentation from the archives. It’s almost fifteen (15) years old but some of the software discussed is still used for open source monitoring (although with updates). The document conversion wasn’t terribly exciting as this presentation used DocBook XML rather than SGML. It’s based on the docbook-slides stylesheet, but… Continue reading Archives: Linux Network Monitoring

Windows and Linux in One

These are some personal notes about setting up a very nice combined Windows and Linux productivity and development environment. It uses
open source software combined with some key proprietary pieces on a single machine and avoids the hassles of a full blown virtual machine. It is important to note this environment is geared to those who are used to the Linux ecosystem and are migrating to the new hybrid model.

Raspberry Pi as an Ansible Server

As a base service for bare metal infrastructure I prefer my provisioning and configuration management servers to be bare metal which can be accessed without requiring other hosts or infrastructure. For small deployments the Raspberry Pi makes a great choice because it is inexpensive, uses little electricity, takes little space, and yet has enough power for the relatively low demands placed on the server (which also makes a full x64 server overkill).
